Abstract

Liquid crystalline medium (A) based on a mixture of polar compounds with positive dielectric anisotropy, comprises one or more polar aromatic compound (I) and 6 binuclear compounds e.g. (II) and (III). Liquid crystalline medium (A) based on a mixture of polar compounds with positive dielectric anisotropy, comprises one or more polar aromatic compound of formula (I) and 6 binuclear compounds of formulae e.g. (II) and (III). R 1>halogenated or unsubstituted 1-15C alkyl- or alkoxy group, where one or more CH 2 group in the residue is replaced by -Ctriple boundC-, -CH=CH-, -O-, -CO-O- or -O-CO-, where O atom is not connected directly; X : F, Cl, CN, or halogenated alkyl, alkenyl, alkoxy or 6C alkenyloxy group; L 1>, L 2>H or F; and R 2>, R 3>H, CH 3, C 2H 5 or n-C 3H 7. An independent claim is also included for an electro optical liquid crystal display containing (A). [Image] [Image].
